Toddlers displaying extremely inhibited behavior may be at risk for becoming socially withdrawn. However, behavioral inhibition may be a multifaceted characteristic, and its concurrent relation to toddler wariness with peers has not been examined. In this study, 108 toddlers (54 females) and their mothers were observed in novel situations involving unfamiliar settings, adults, and peers. Vagal tone, temperament, separation-reunion behavior, and maternal oversolicitousness also were assessed. There was little consistency of inhibited behavior across the 3 situations. Consistently inhibited toddlers had fearful temperaments, showed distress following maternal separation, and had mothers who were warm and controlling but unresponsive to children's cues during interaction. Toddlers with highly fearful temperaments and highly oversolicitous mothers were the most inhibited across contexts.  相似文献

ITAs often experience particular difficulty balancing their roles as teachers with their roles as students. Student communication skills training is warranted for ITAs because it may be more motivating than instructional skills training, because it captures an otherwise elusive segment of the clientele, and because learning can transfer to ITAs' own teaching repertoires. Such a program can begin with a focus on naming and social identity. The bulk of the program focuses on communication practices for participative learning such as small group problem solving and whole-group responding. A typical workshop concludes with a forum for student concerns, often focusing upon how to interact with one's academic advisor.He obtained his Ph.D. in 1978 at the University of Minnesota. Among the courses he teaches are offerings in intercultural communication, applied linguistics, and composition research. He has also conducted research pertaining to perceptions of international instructors.  相似文献

In this study, I capitalize on a natural experiment to examine the effect of federal Pell Grant eligibility on college enrollment for students who graduated from high school in spring 2004 and who completed the Free Application for Federal Student Aid (FAFSA). Data from the Education Longitudinal Study of 2002 are used to array students on the continuous Expected Family Contribution (EFC) variable, attained from the FAFSA, and divide them into two categories—those with an EFC at or below the federally designated amount for Pell eligibility, and those above. This regression-discontinuity approach allows me to measure whether students who vary regarding their Pell Grant eligibility, but who have essentially identical family incomes, differ in their college enrollment rates. I find no effect. While confirming prior studies examining the impact of the Pell Grant on college enrollment for traditional students, this finding remains inconsistent with findings on other need-based grants. This result suggests that the minimum Pell Grant amount, currently less than 10% of an average college’s tuition and fees, may be insufficient.  相似文献

农村养老受到诸多社会力量的支持,政府为农村养老提供了政策支持;家庭养老作为目前农村最重要的养老力量,具有广泛存在的空间和合理性;老年人自给自足也能保障晚年生活。但是这些力量也都有自己鞭长莫及之处,在农村集体经济发展、村集体自主管理力量不断加大的同时,由村集体或村民自创的社区养老服务的新形式成为一种重要的养老力量,综合分析各种农村社区养老要素及个案来看,农村社区养老服务将在今后有着广泛的发展空间。  相似文献

The study examines selected roles of the information sector in the national economy. Among the findings are the following: (1) the information sector conducts relatively little international trade, in comparison to its domestic activity. Roughly 12% of U.S. exports are attributable to the information sector; over 97% of the sector's output is sold within the U.S.; and the sector's exports account for only a small fraction of 1% of GNP. (2) The historical pattern of employment shows that the portion of information workers has risen from 8% of the U.S. work force in 1870 to 41% in 1970. Relatively little of this growth is the result of new technological innovations such as telephones, radio, television and, more recently, computers. Rather, the growth of public and private bureaucracies, which now total 26% of our total work force, largely explains the growth of the sector. (3) Unemployment within the information sector has consistently been lower than in either the manufacturing or agricultural sectors of the national economy. (4) Since 1967, the high technology elements of the information sector, such as electronic components, computers and telecommunications equipment have experienced appreciably less price rise than has the economy as a whole. However, over the same time period, the service elements of the sector, including finance and insurance, education and medical care, have experienced greater rates of inflation than has the economy as a whole.  相似文献
